Tier: enthusiast — a high‑wattage, Gold, fully modular supply built to power high‑end single‑GPU rigs with extra headroom. It’s well‑suited to high‑end GPU builds and headroom/overclocking in full‑size ATX cases. Note it lacks native 12VHPWR/ATX 3.x; if needed, use Corsair’s Type 4 12V‑2x6/12VHPWR cable sold separately. Unique: a 135 mm magnetic‑levitation fan with zero‑RPM mode.
